Hide div withing iframe
提问by out_sider
I have an iframe and I'd like to hide a div whithin it, so bascily people can't for example sign out in the iframe.
我有一个 iframe，我想在它里面隐藏一个 div，所以基本上人们不能例如在 iframe 中注销。
What I did was :
我所做的是：
<script type="text/javascript">
function changeCSS(){
frame = document.getElementById("myIframe");
frame.document.getElementById("guser").style.display='none';
}
</script>
<iframe onload="javascript:changeCSS()" id="myIframe" src="{$docUrl}" width="800px" height="600px"></iframe>
But I can't get it to hide the div "guser".
但我无法让它隐藏 div“guser”。
If anyone could help I'd be very much appreciated.
如果有人可以提供帮助，我将不胜感激。

Different hostname or domain?If you don't have control over the framed page, there's nothing you can easily do.If you do have control over the framed page, try checking insidethe frame whether the page is framed or not (this is based on a well-known frame-busting code):
不同的主机名或域？如果您无法控制框架页面，则无法轻松执行任何操作。如果您确实可以控制框架页面，请尝试在框架内部检查页面是否已框架（这是基于众所周知的框架破坏代码）：
function changeCSS() {
document.getElementById("guser").style.display = 'none';
}
if(top != self) {
if(window.addEventListener) {
window.addEventListener('load', changeCSS, false);
} else {
window.attachEvent('onload', changeCSS);
}
}
Edit: Now that you mention Google Docs, I believe the above code won't work.
编辑：既然你提到了 Google Docs，我相信上面的代码是行不通的。
